  [OpenMP] Introduce the ompx_name clause for kernel naming

This adds support for the ompx_name clause that allows users to specify
custom kernel names for OpenMP target offloading regions. The clause
accepts a string literal and overrides the default compiler-generated
kernel names.

Example usage:
  #pragma omp target ompx_name("my_kernel")
  { ... }

The clause is supported on all target directives including:
- target
- target parallel [for] [simd]
- target simd
- target teams [distribute] [parallel for] [simd]
- target loop
- target parallel loop
- target teams loop

Changes include:
- Added OMPXNameClause to Clang AST
- Added clause parsing and semantic checking
- Added UserProvidedName field to TargetRegionEntryInfo
- Updated kernel name generation to use user-provided name when available
- Added comprehensive tests in clang/test/OpenMP and offload/test
